Since the clamping device 400 is disposed on the base 300 and can clamp the drill 200 to be machined, and the grinding wheel device 600 is disposed on the base 300, the drill can be ground by the grinding wheel 100. Since the ejector 500 is disposed on the machine base 300 and is used for supporting the drill bit 200 to be processed from a direction perpendicular to the axial direction of the drill bit 200 to be processed, it is possible to prevent the portion of the drill bit 200 to be processed, which is exposed from the clamping device 400, from being affected when the grinding wheel 100 is ground, thereby improving the grinding quality of the drill bit.
